Constant 12v not working throughout entire car

My buddy has a 85 z28 and the car has no door lights unless you turn on the key switch and the radio has no memory either. I pulled the radio and the yellow constant wires are tied in with the red ignitin wires with a big house wire nut. I tested the yellow constant power and it's completely dead. Any ideas how to fix? Or anyone with a similar problem?

Check the "CTSY" (as in, "courtesy light") fuse

That was the very first thing I tried, the fuse is good

Lets Have A Little Courtesy

Because that fuse looks good, probe both sides of it.

If there is power both sides, you have a broken wire/bad connection where it branches out.


Happy Racing !
